I am trial factoring using Prime95, version 23.8.1, on on old 233 MHz
machine running Windows 95. On the number I am working on now I am
getting a series of "Incorrect factor found" errors. Here is an extract
form the results.txt file.
[Mon Oct 10 02:13:57 2005]
ERROR: Incorrect factor found.

ERROR: Incorrect factor found.
I am also getting some strange figures in the onscreen progress report,
as the extract below shows. The percentage complete figure goes down as
well as up and sometimes gives strange figures such as -1.#J%. The time
per step also has some crazy numbers, eg 3613650 secs is over a month.
